# Sending messages

Everything on the Send New tab: your spreadsheet, merge fields, replies, opt-outs, scheduling, preview and send.

Every send happens on the **Send New** tab of the ExcelSend pane. These pages follow the tab from top to bottom, in the order you fill it in.

## Pages in this section

- [Merge fields](https://excelsend.com/docs/sending/merge-fields/): Put a value from each row into its message with ^^ColumnHeader^^, and control how dates and amounts appear.
- [Opt-outs](https://excelsend.com/docs/sending/opt-outs/): Add an opt-out link to messages, and how opted-out numbers are blocked from later sends.
- [Prepare your spreadsheet](https://excelsend.com/docs/sending/prepare-your-spreadsheet/): How to lay out a sheet so ExcelSend reads it correctly: headers in row 1, one contact per row, and which rows it sends to.
- [Preview and send](https://excelsend.com/docs/sending/preview-and-send/): Check every message, its size and the total price, then send and get a job number.
- [Replies and Sender IDs](https://excelsend.com/docs/sending/replies-and-sender-ids/): Choose whether contacts can reply, or whether messages come from your organisation name, and what your country allows.
- [Schedule a send](https://excelsend.com/docs/sending/schedule-a-send/): Send messages now, or at a set date and time up to 14 days ahead.
- [Write your message](https://excelsend.com/docs/sending/write-your-message/): Compose the text, add emojis, read the size line and save messages you use again.
